What size is a halls bed? UK student accommodation bed sizes explained

Updated 23 September 20263 min readBy the Chapter team, Yorkshire

Every August the same question: what size sheets, duvet and topper do I buy for a halls bed I have not seen? The answer depends on the university and often on the block, so this guide gives you the sizes in use, how to find out which you have, and what to buy for each.

The three sizes in UK halls

SizeDimensionsWhere you find itBedding to buy
Standard single (3ft)90 × 190 cmMost university-owned halls, most older blocksSingle fitted sheets, single duvet
Small double (4ft)120 × 190 cmMost purpose-built private student accommodation built since about 2010, many en-suite rooms and studiosSmall double fitted sheets (a double fitted sheet will not fit; a double duvet is fine)
Small single (2ft 6)75 × 190 cmSome older halls, some converted buildings, occasionally in shared roomsSmall single fitted sheets (a standard single will be loose but usable)

A very few halls have full doubles (135 × 190 cm) in studios or postgraduate flats; if the room is marketed as a studio with a "double bed", check whether that means 4ft or 4ft 6.

How to find out

  1. The accommodation listing. Universities and private providers usually state the bed size on the room page or the inventory. "Three-quarter bed" means 4ft small double. "Standard single" means 3ft.
  2. The accommodation office, by email, with the room type or block name. They answer this every summer.
  3. Last year's residents, in the university's halls Facebook group or subreddit. Ask for the block, not the university.
  4. On arrival, a tape measure across the mattress, before unpacking the bedding.

If you cannot find out, buy for a 3ft single: a single fitted sheet stretches onto a small double badly but usably for a night, and a small double sheet on a single bags.

Mattress depth

Halls mattresses are shallow, typically 15 to 18 cm, and often in a waterproof cover. Fitted sheets are all deep enough for this; it is the topper that changes things: a 5 cm topper on an 18 cm mattress needs a sheet with a 25 cm pocket, which most standard sheets have.

What to buy for each

  • Two fitted sheets in the right size (one on, one in the wash).
  • A protector, cotton or Tencel, which goes over the topper if you have one, because the halls cover is plastic.
  • A topper, 5 cm memory foam or latex, if the mattress is firm but sound; see which topper for a halls bed.
  • A duvet one size up if you like it wide: a double duvet on a single bed is a known student move.
  • Pillows. Halls pillows are thin.

If the halls bed is not a standard size at all

Some converted buildings have odd lengths (180 or 200 cm) or widths. A stretch fitted sheet copes with a few centimetres either way. For anything stranger, a made-to-measure sheet is cheaper than it sounds.

After halls

Second-year houses have whatever the landlord bought, usually a 3ft single or a 4ft small double, sometimes a double, and usually older than the halls mattress. The bedding you bought for halls carries on if the size matches. If the second-year mattress is the problem, that is when a proper mattress becomes worth it; see the student mattress guide.

How we fit in

The Uni Student is sold in exactly the two halls sizes, 3ft single and 4ft small double, and delivered flat to halls the working day before move-in if you tell us the date.

The short version

  • 3ft single in most halls; 4ft small double in newer private blocks; 2ft 6 in a few older ones.
  • Check the listing, then the accommodation office, then a tape measure.
  • Buy protector, sheets and a topper for the size; a double duvet on a single is fine.
